Processing technology of ultra-fine silver-plated alloy wire

Abstract

The invention belongs to the technical field of wire rod processing, and in particular relates to a processing technology of ultra-fine silver-plated alloy wire. It solves technical problems such as unreasonable existing technologies. This processing technology includes the following steps: A. Silver plating; B. Multiple wire drawing and heat treatment; C. Tube heat treatment and wire releasing; D. Stranding and untwisting. Compared with the existing technology, the advantages of the ultra-fine silver-plated alloy wire processing technology are: through the improved wire drawing and annealing processing technology, the produced alloy wire has small wire diameter, high strength and high pass rate. The minimum single wire diameter can reach 0.015mm, the conductor strength can reach more than 800N / mm, and the product qualification rate can be increased to 99.5%. By adopting back-twist stranding process, the problem that the conductor is easily loosened or even broken due to stress distortion during stranding is improved, and the produced strand conductor has high roundness, compact structure, and high tensile strength.

Description

technical field [0001] The invention belongs to the technical field of wire rod processing, and in particular relates to a processing technology of ultra-fine silver-plated alloy wire. Background technique [0002] Recently, with the rapid development of notebook computers, medical equipment, digital cameras, mobile phones and other products, coupled with the launch of 3G mobile phones in the international market, the amount of ultra-thin coaxial cables used to connect mobile phone CPUs and liquid crystal (LCD) also increased sharply. In order to avoid the interference between the various components in the equipment, a super-thin coaxial cable product with faster transmission speed, larger capacity, stronger anti-interference, bending resistance and vibration resistance began to quickly replace the current Flexible printed circuit (FPC) and FFC used. As one of the core materials of ultra-thin coaxial cables and electronic wires, ultra-fine surface-coated silver alloy wires...

AI Technical Summary

Problems solved by technology

However, due to the high strength of the high-strength alloy conductor, it is easy to damage its own material during the wire drawing process, causing the conductor to be strained, the strength is reduced, and the performance is deteriorated.

For this reason, people have conducted long-term explorations and proposed various solutions, but none of them have achieved satisfactory progress.
